The present invention relates to a novel polypeptide that binds selectively to mouse or rabbit immunoglobulin G. More specifically, the present invention relates to a polypeptide that binds to mouse or rabbit immunoglobulin G, a polynucleotide encoding the polypeptide, an expression vector comprising the polynucleotide, a transformant introduced with the expression vector, a method of producing the polypeptide using the transformant, and a composition for immunoassay comprising the polypeptide. The novel peptide according to the present invention binds specifically to mouse or rabbit immunoglobulin G, can replace conventional expensive secondary immunoglobulin G, and can be used in various biological immunoassays. In addition, a conjugate of the polypeptide of the present invention and immunoglobulin G is useful for fabrication of various immunosensors/immunochips and for drug screening.

An apparatus for generating a time slot in a home network system using home PNA 2.0 protocol and a method thereof are provided. The apparatus for generating a time slot includes a signal analyzer which receives a carrier sense signal indicating whether or not data exists on a network line, generates a counter control signal according to the level of the carrier sense signal, outputs a state signal for indicating whether or not effective data is received, whether or not data collision occurs, or whether or not an error happens to the carrier sense signal and a time counting value for generating a time slot using counter values provided in response to the carrier sense signal, a counting unit which counts a clock signal in response to the counter control signal and outputs the result of the counting as the counter values with respect to the length of a first level of the carrier sense signal and the length of a second level of the carrier sense signal where the second level is complementary to the first level, and a time slot generator which has regulations related to the period of time of each section of a time slot, generates a time slot according to the state signal output from the signal analyzer using the time counting value to meet the regulations, and stops generation of the time slot in response to the state signal for indicating that an error happens to the carrier sense signal. Accordingly, it is possible to generate a reliable time slot by controlling generation of a time slot based on whether or not an error occurs to a carrier sense signal being currently received and taking the amount of time delayed inside a device including the apparatus for generating a time slot into consideration.

Apparatus for generating time slot in home network system and method thereof

A modular-type home gateway system that includes a HomePNA controller connectable to an existing home telephone line, for providing a home network interface; an ADSL controller connected to a prior outdoor telephone line for providing an access network interface; and a system controller for controlling the HomePNA controller and the ADSL controller, the HomePNA controller and the ADSL controller formed as a modular type that are detachably connected to the system controller through a predetermined interface, and that provides a bridge function between a home network and an access network. The modular-type home gateway system provides a plurality of informational terminals connected to the home network with various data sharing functions (e.g., Internet service sharing function, a peripheral device sharing function, file/and application program sharing function, and an entertainment service sharing function like a network game) for not only narrow-band service data but also wide-band service data.
